Default browser changes to none

Dear,

I am building a kiosk app in desktop mode that call for a custom-made browser.  With a few registry hack, I can force it to be a default browser in that current kiosk profile.  Upon logon, restart etc, the custom-made browser remains the default browser.  Since I bought and installed Inteset, everytime the program run, logged off and logged back in, the default browser became empty and everytime the icon in the kiosk app is pressed, it ask for which browser.   Can you enlighten me why this is the case?  Also, is there any way to stop it from altering or resetting default browser?

I look forward to your assistance.

By theway, forgetting to mention that I am using Windows 8.1 Pro in HP Envy 27 27-K300a.

Thank you.

What is the Windows Registry entry you're using to change the default browser?

So far the way I wrote it is my program is sort of sitting by replacing Firefox browser.  Basically I turned the important registry of Firefox to be a default browser has been replaced by my browser.  Then, I just configured the default browser under PC Settings as usual in Windows 8/8.1.

Is there any other setting that I should consider to possible fix this issue?

Thank's for your prompt reply.

Regards,

Iman

Is IE Lockdown enabled in your setup? It's not clear what Edition of Secure Lockdown you're using. If you describe the indicate the actual Windows Registry setting you're modifying, we can let you know if it's one being affected by Secure Lockdown.

Hello,

Thank''s for your reply.  Initially I bought Secure Lockdown Standard edition however upon realizing the more features MultiApps have I decided to use this version now.

No, I didn''t use IE or Chrome for it.  I ran into this app due to searching for a better way to hack an All-In-One desktop to turn it into a kiosk for a prototype that we develop.

The symptom I ran into somehow was similar to when I ran this desktop app in Windows 10.  When I clicked this prototype kiosk to call a browser based link, at the very first time when the app fires up, it will work.  It will correctly called simplebrowser_wpf.  The next click always default to ask which browser to use to open the http link. and so is the subsequent clicks.  I have installed it in Windows 8/8.1, once the custom-made browser app is set to be default program, it will stay that way in a stable way.

I am not quite sure which registry you meant however I took a liberty to list all the registry keys that has filename of the custom-made browser we are currently developing.  Here is the list:

By the way, the prototype is built on Adobe AIR with icons/links that opens up to a custom-made browser.
